The name of the Catenary Group—consisting of a chair, an ottoman, and a coffee table—comes from the term for the curve of a rope or string that hangs freely from two fixed points of different heights. This catenary at the same time describes the essential principle behind the construction of the chair. In the chrome frame, two cables are hung that are fixed at only two points from the front to the back. These two cables, which follow the course of a catenary, hold the eight parallel seat cushions.
